Fallout 4: Nick Valentine Affinity Guide, Personal Quest & Far Harbor Integration

【Information as of June 3, 2026】
Fallout 4 is a single-player RPG and does not use a seasonal system. The latest major update was the Next-Gen Update, released on April 25, 2024, primarily focused on performance improvements, bug fixes, and some new content additions. It does not include direct balance adjustments to Nick Valentine's performance or quests.

In the wasteland of The Commonwealth stands the neon city of Diamond City. In a corner of it, a man runs the "Valentine Detective Agency" – Nick Valentine. He's no ordinary private detective; he is a unique prototype synth, housing the memories of a pre-war detective from Chicago P.D. A key figure in Fallout 4's main story, his cynical demeanor and hidden sense of justice have captivated many players. This article provides a complete guide to efficiently raising the affinity of this excellent companion, Nick Valentine, completing his personal quest 'Long Time Coming' to bring closure to his past, and maximizing his true potential in the 'Far Harbor' DLC.

Who is Nick Valentine? Your Synth Detective Companion

Nick Valentine is a synth private detective operating in Diamond City. Players can recruit him as a companion by rescuing him during the main quest "Unlikely Valentine." He is a prototype synth, implanted with the memories and personality of the original Nick Valentine, a pre-war detective from Chicago P.D. As such, despite being a synth, he possesses extremely human-like thoughts and emotions.

In combat, he wields his trusty Pipe Revolver, but his true value lies more in his special abilities than his combat prowess. His SPECIAL stats in Perception and Intelligence are set high, making him incredibly reliable for exploration. In particular, his ability to attempt hacking even difficult terminals will be a great help in acquiring items and advancing quests. Furthermore, as a synth, he has complete immunity to radiation and poison, powerfully supporting the player even when exploring contaminated areas.

How to Raise Nick Valentine's Affinity?

Nick's affinity increases through actions that align with his underlying "sense of justice," "investigative spirit," and "empathy for synths." Gaining his trust not only triggers his personal quest but also deepens the immersion of your journey together.

Actions Affecting Affinity List

To maintain a good relationship with Nick, it's important to understand his values. Refer to the table below when making choices.

Efficient Ways to Raise Affinity

Here are a few specific methods to intentionally and efficiently raise Nick's affinity.

1. Hack terminals frequently: This is the easiest and most reliable method. Nick's affinity increases upon successful terminal hacks, and there is no cooldown period for this action. When exploring new locations, actively seek out and hack terminals. Even simple ones will suffice.
2. Consistently choose kind options: In quest dialogue, always choose options that help people or show compassion. He dislikes selfish attitudes like demanding rewards or expecting something in return. Choices like "I'll help" or "Of course" will lead to affinity gains.
3. Defend synths: The Commonwealth has many issues surrounding synths. In Institute or Railroad-related quests, if you make statements affirming the rights and existence of synths, Nick will strongly empathize with you.

Personal Quest 'Long Time Coming' Walkthrough

As your bond with Nick deepens, a personal quest deeply tied to his past will trigger. This is one of the most touching quests in Fallout 4.

Quest Trigger Conditions

To trigger this quest, you must meet the following two conditions:

• Raise Nick Valentine's affinity to 750 or higher.
• Have completed the main quest "Dangerous Minds."

Once these conditions are met, speak to Nick, and the story begins, pursuing his 200-year-old nemesis, the gangster 'Eddie Winter.'

Walkthrough Chart

1. Collect Eddie Winter's Holotapes: The objective of the quest is to collect 10 of "Eddie Winter's Holotapes" (numbered 0 to 9) left in police stations and related facilities across The Commonwealth. Markers will appear, making it easy to locate them. You will visit places like the BADTFL Regional Office and Natick Police Department.
2. Give the Holotapes to Nick: Once you've collected all 10 holotapes and given them to Nick, he will analyze the information on the tapes, discover that Eddie Winter's hideout is "Andrew Station," and pinpoint the passcode to open the hidden door.
3. Head to Andrew Station: Andrew Station is a raider stronghold. Clear out the enemies in the station with Nick and head for the deepest part.
4. Confront Eddie Winter: Beyond the hidden door, you will confront the ghoulified Eddie Winter. Defeat him and all his subordinates.
5. Quest Completion: After defeating Eddie Winter, you will obtain his powerful unique weapon, "Eddie's Peace." Then, a final conversation with Nick will complete the quest, lifting his long-standing burden.

Max Affinity Perk and Role in DLC 'Far Harbor'

By completing his personal quest and maximizing your bond with Nick, players receive special benefits. Furthermore, he plays an extremely important role in a specific DLC that no other companion can.

Max Affinity Perk 'Close to Metal'

The Perk gained by maximizing your relationship with Nick makes exploration more comfortable.

• Perk Name: Close to Metal
• Effect: Increases the number of terminal hacking attempts by 1 and reduces the lockout time (reset after failure) by 50%.
• Acquisition Condition: Complete the personal quest 'Long Time Coming' and then maximize Nick's affinity (1000) during the subsequent conversation.

Special Role in DLC 'Far Harbor'

When playing the 'Far Harbor' DLC, it is highly recommended to bring Nick as a companion. He is deeply involved in the DLC's story, and his presence significantly changes the story experience.

DiMA, the synth leader you meet in Far Harbor's main quest, is a prototype synth just like Nick, a brotherly figure to him. By bringing Nick along, a vast amount of special dialogue is added between him and DiMA, allowing you to learn more deeply about their past and the mysteries hidden in Far Harbor. You can obtain information that delves into the core of the story, which you would never hear with other companions, so if you want the best immersion, there is no other choice but Nick.

Regarding Romance

While you can enter romantic relationships with many companions, Nick Valentine is unfortunately not a romance option. His relationship with you is portrayed as the best companion and a close friend bound by a strong bond.

Conclusion

Nick Valentine is not just a combatant in the world of Fallout 4. His hacking ability expands the scope of exploration, and his justice-driven demeanor provides guidance for the player's role-playing. The personal quest 'Long Time Coming' is a touching story that delves into his past and struggles, and the Perk 'Close to Metal' obtained after completion is also very practical. And above all, in the 'Far Harbor' DLC, he becomes an indispensable guide for the story, enriching the story experience many times over. Be sure to travel The Commonwealth with Nick Valentine and experience an unforgettable adventure with the synth detective.
